Glass Fibre Product Forms
topic
Commercial forms: continuous roving (parallel filament bundles, 100-10,000 tex for pultrusion, filament winding), chopped strands (3-50 mm length for BMC, SMC, thermoplastic compounding), woven fabrics (plain, twill, satin weaves for hand layup, prepregs), multiaxial non-crimp fabrics (0°/90°/±45° for high-performance composites), chopped strand mat (randomly oriented for spray-up, hand layup), surface tissue/veil (smooth surface finish), and milled fibres (<1 mm for filler applications).
Role
Diverse product forms enable optimized reinforcement architectures for different composite manufacturing processes (pultrusion, RTM, compression molding, hand layup) and performance requirements.
